METHOD OF TREATING OLDIRON AND STEEL PIPE.

Patented A11 4, 19114.

Application filed July 26, 1913. Serial No. 781,348.

0 all who/nit may concern do it known that I, DANIEL E. PHILLIPS, acitizen of the United States, residing at Cleveland, county of Cuyahoga.and State of Ohio, have invented certain new and use ful Improvements inMethods of Treating Old Iron and Steel Pipe, of which thcfollowing is aspecification.

My invention relates to an improved method of treating old iron andsteel pipe.

The object of my invention is to provide a method of treating olddiscarded iron and steel pipe whereby the same may be readily formedinto bars for various uses wherein puddled iron has heretofore beenused.

Other objects will appear hereinafter.

My invention consists generally in tumbling the pipes to remove dirt andrust, heating the same in a furnace, flattening an end of each of thepipes and passing the pipes through rollers or dies to form the sameinto bars.

My invention will be'more readily understood by reference totheaccompanying drawings forming a part of this specification and inwhich:

Figure 1 is a diagrammatic side elevation of apparatus for carrying myimproved method into practical operation, Fig. 2 is an end elevation ofthe tumbler, Fig. 3 is an end elevation of the furnace, Fig. 4: is anend elevation of the hammer or parts for flatten- --ing the ends of thepipes, Fig. 5 is an elevation of the rollers such as may be used in theprocess, Fig. 6 is a view similar to Fig. 1 illustrating a slightmodification of my invention, Fig. 7 is a detail view illustrating astill further modification, Fig. 8 is a detail view illustrating oneportion of the process, and Figs. 9 and 10 illustrate a furthermodification.

Referring now to the drawings 1 indicates the tumbler which comprises ahollow rotary cylinder 2 supported upon a suitable base or frame 3. Thepipes are first placed in the cylinder 2 and said cylinder rotated totumble the pipes for the purpose of removing dirt and rust from thesame. a pulley 1 being provided on the shaft of the cylinder to affordmeans for rotating the latter. Afterthe pipes have been tumbled they areconveyed on the table 5 provided with rollers 6 to a furnace 7 providedat each end with doors 8 and 9 respectively, supported by acounter-balanced lever 10. If the pipes are very dirty or rusty the useof the table 5 1s dispensed with and the pipes are turned on end aftertumbling to remove the dirt and rust before placing them in the furnace.In the furnace the pipes are thoroughly heated to the desired degree andare conveyed upon a table 5', similar to the table 5, to a hammer orpress 11 where the forward ends of the pipes A are flattened tofacilitate their entrance between the rolls or the dies of the shapingmachine as illustrated in Fig. 8.

12 indicates the shaping machine which as above mentioned may be eithera die or dies or rollers. In Fig. 5 I

have illustrated the same as rollers, and these are formed of a pair ofsuperimposed rolls each formed with a series of annular ribs orenlargements 13 defining a series of annular channels 14L between them,and arranged so that the ribs of one roll enter the channels of theother. By this construction the pipes, as they pass between the rollsare confined between the annular ribs so that the bars formed therebyare of uniform width. The ribs and channels in the rollers are ofdifferent widths and depths to accommodate pipes of various sizes and toform bars or flats of different dimensions. Any number of sets of rollsmay be employed as found advantageous in practice. Furthermore ifdesired smaller pipes may be placed within those of larger diameterbefore heating as shown in Fig. S); the ends being flattened in themanner above described, and as shown in Fig. 10; then rolled or passedthrough the shapers. In this way, two, three, four or more pipes may berolled into one bar. If preferred a num ber of pairs of rollers 12 maybe employed, the pairs being spaced a sufficient distance apart topermit the work passing from one pair before entering between the nextpair, as shown in Fig. 7; by which arrangement the bars B. pressed bythe first pair may be turned before entering between the next pair. Thisis particularly advantageous when a plurality of nested pipes are beingrolled, so as to form a uniform homogeneous mass.

In the modified process shown in Fig. 6, the pipes are taken from thefurnace and placed on a die or form 15, of a length as great as that ofthe pipes and there pressed into shape by hammering or by a press 16.

By the use of the method above described, old iron pipes which are insuch condition that they have heretofore been considered fit for thescrap heap only, may be formed into high grade iron bars for Varioususes.

1 claim 1. The herein described method of treating old iron and steelpipes consisting of tinnbling the same, heating the pipes and passingthe same through shaping machines.

2. The herein described method consisting of heating old iron and steelpipes, flattening the ends and passing the same through shapingmachines.

3. The herein described method of treating old iron and steel pipesconsisting of tumbling the same to remove the dirt and rust, heating thepipes in a furnace, flattening the ends and then passing them betweenshaping rollers,

i. The herein described method of treating old iron and steel pipesconsisting of heating the same, flattening the ends and 7. The hereindescribed method consisting 35 of placing pipes of different diametersone Within the other, heating, flattening the ends and then passing thesame bet-Ween shaping rollers.

In testimony whereof I have signed my 40 name to thls specificatlon 1nthe presence oi two subscribing Witnesses.
